You can add J.M. Hatchery to your list of those still selling muscovy ducklings. We received ours mid-March but I believe they are still selling. You just have to call them on the phone directly if you want to order them and you can't order direct from their website.
I don't know about the quality. I hope good! They are supposed to be large and are white.
